' Thesubject of my invention is an improved method of, and machine for,cultivat y ing land.

According to the'new process the ground is mechanically scraped by meansof suitable implements, and the soil so scraped is thrown upward." 4 rThefnfiachine for carrying out the process is furnished withari-endless" apron, which can be set in motion by ineansof la motor,employed to drive the machine. On' this apron' the operative implementsare disposed insuchrman'n'er that-"they can yield in all diY- rections.f l

Certain practical embodiment-tact the invention are illustrated in theaccompanying drawing. I r

,Figure 1 is an elevation, showing one torni of constructionof themachine, such parts as are not necessary for explanation ot theinventionvbeing omitted. Fig. 2 is a plan of the 'left-hand portionot'Fig.v 1, a part of the apron being broken away to display underlyingparts. Figl is a vertical see tional view illustratinga modifiedconstruction of drum withv sieveJf-F ig. i is a front, view of a sinuoussieve. Figs. 5-9a show various forms of implements. Figs. 10-15illustrate several forms of construction of the endless apron. Fig. 16illustrates diagramrnatically two ways of disposing the implements uponthe endless apron..

Referring to Figs. 1 and 2, there are provided at each side of thetraine 1 'of a motorcart-bars 2' whose .upper endsare journaled on thepins 3, while the other endsare connected by a shaft 5. On the one upin'3 there is mounted a` sprocket-wheel 4C, which is driven. by ,themotor, through', thev agency of "5a., ATo tlie.,shat 5 there is alsokeyed ar speculation bf Letters retener. f

tr`undle-drum 8. Further, there is loos-ely mounted on this shaft 5 theone end of eachof two short frame-'bars 9, while the other ends of thesebars are connected by a shaft 10. Between the bars 9 there is mountedaroller 12 loaded with weights 11.' A@n the shaft 10 there is mountedasecond trundledrum 13. Around the two drums 8, 13 there runs an endlessapron 14, provided with Scrapers 15. 16 are ropes for elevating theframes 2 and 9, and the dot-and-dash lines in Fig. 1 show the frame 9 inits raised 'posit-ion.' 17 are arms extending rearwardly of the drum 8for the purpose of sustaining a-sieve. g

When'the sprocket-wheel'4 is driven by the motor, the drum 8 revolvesand drags the network 14 lover the ground. The Scrapers thus' dig intothe -soil,'rake along the scraped material, and throw it up behind thedrum 8. Should there be stones in .the way, the Scrapers will. pass overor around them, as the network admit-s of their yielding in alldirections, so thaatthe stones will gradually loosen andbe carried alongby the Scrapers. The network during such working .adapts itself to thesurface of the ground. If the lattershould be so hard that the momentumof the apron is insuliicient to enable proper operation of the Scrapers,the roller 12 mustbe lowered upon theapron, sol as to load it. It' thesoil is to be'scraped to avery considerable `depth, the frame 9 mustbedrawn up, whereby the area ofthe scraping-surface is diminished,4while the ypressure at the place of work is increased.

Referring now to the modifications shown l in Fig. 3, the network 14 ispassed around merely a single drum 8, which rotates with the shaft 5. Onthis shaft, at a suitable disl tance apart, two polygonal disksare-secured, which at their corners are unitedby trundles 19, so thatakind of reel is constituted.- The trundles 19 are held by adjustablebrackets 20. Around this reel the network' 14 is applied, and rigidly orresiliently connected with the trundles .19. at suitable places.' 1Whenthereel 8 rotates, the network'l-t has thetendency to fly out from'thecenter of'rc tation; 'it thus lhears closely against the ground andscrapes away 'everything that obstructs it.V The material is thrown 11pin .the same manner as in theconstruction with .two drums. In bothcases, and also with Qtherarrangements of the scraping-network,individual Vpcmtions of the latter can, if

' and 13). The network may also consist entirely (Fig. 14:) or partly'(Fig. 15) of springs. In the case of sandy soils relativel bluntScrapers prove adequate. If, however, turf, foliage, stubble, stalks, orthe like, havnv `to be out through, such ebstructions mustl first bereduced, that is, the Scrapers must break them through and then cutthem, Vloefore they are mixed with the soil. In such cases, Scraperswith cutting-edges, as for example `as those shown in Figs. 5 and 6,should be employed. If the scraping network is to be employedy forvarious classes of work, the Scrapers must be so secured as to\bereadily removable. for instance when the scraper's have also to scrapemanure, conveyed by the cart and miX it *with the soil.

In tlf 'present method, the earthA is not f' cut out i cylindricalpieces (as is the case with prior machines, which do not scrape, butrather 'g and pierce), but is removed in a form suited to the resistanceoffered by the soil, and r eatedly changing.

i The scraped aterial may be thrown upv in the following nner: Theremnants of vegetable matter QFig. 1) are overcome by the resistance ofthe air and rapidly fall to the ground. Fi e, pulverized earth ylikewise descends rapndly. Clods and stones e, on the other hand,arehurled to a great distance andfall out on top at the back. In autumn,and in turningover frosty land, this method of'working may be suitable;in warmer countries and fon sowing, it would be suitable, as in suchcase it is the fine earth that is required on the top. For this purposesieves 23 (Fig. 3) are stretched between thearms. 17. If thesesorting-sieves 23 are` fiat, the scraped material passing through ithemwill naturally lie evenly on the land.4

lhe clods and stones being the heaviest -bodies -are vhurled to thehighest-part of the sieve, but cannot drop through the meshes andmust'therefore return and have a considerable dista-nce to travel. Theytherefore fall in front of the sieve, at the deepest 'This is requisite,

vplacfffhe pulverized earth y? on the other this manner :naturally onlyline earth col-4 lects in the furrows, while the ridges are built up ofcoarse material also. As Fig. 16 shows, different kinds of Scrapers maybe disposed at definite parts of the apronr I claim as my invention- 1.A machine for cultivating land, comprising a machine-frame, aroller-frame pivoted to the machine frame, rollers carried ing motion tosaid rollers, an endless belt or apron passing over said rollers, andScrapers attached to said endless belt in such a manner direction.

2. A machine for cultivating land, coniprising a machine-frame androller-frame pivoted to the machine-frame, rollers carried by the saidroller-frame, .means for imparting motion to the said rollers, anendless belt or apron passing over said rollers, Scrapers pivotallyattached to the said endby the said roller-frame, means for impart--that they are free to move in any less belt which latter is in the shapeof a otally connected to the machine-frame, roll--V ers mounted yin saidroller-frame earth engaging means on said rollers, means for actuatingthe said rollers, and a sinuousshaped sieve located rearward of the saidrollers.

In testimony that I claim the foregoing as my invention, I have signedmy name in -presence of two subscribing witnesses.
